Incorporation of High Energy Materials Into High Density Polymers
Abstract
The object of the research was to synthesize high energy, high density compounds, primarily polymers, that could have an end use as solid fuels or energetic binders in cruise missiles. New graft terpolymers were synthesized and characterized, such as EPDM-g-PST and EPDM-g-PMST. Two methods of synthesis were successful: a macromonomer (a polymer containing a polymerizable head group) was copolymerized with ethylene and propylene to lead to the final product, and chlorination of a commercial EPDM allowed the chlorinated sites to serve as cationic initiation points so that grafts could be grown from these sites. The catalyst system Re(CO)(5)C1/C(2)H(5)A1C1(2) promoted the polymerization of strained monomers, such as norbornene and the dimers of norbornadiene. The unusual feature of the polymerization is that the rings of the monomers are retained in the polymer. New methods for producing hafnacyclopentadienes have been developed. All compounds were obtained in high yields. A few potentially polymerizable carborane molecules were prepared but, these could not be incorporated into polymers in sufficiently high amounts.
